Ok I've looked the page you suggest (http://www.william-map.com/ 20100607/1/states.htm) but I don't really understand what you are doing :/
What I have to do : - have a single kml file without altitude informations -- what I've done (the files are now 216KB) - I know gzip but not for Web I don't understand how to use it with GGeoXml - draw the frontier (but this information already appears into the kml file) - draw an overlay on the map that exclude the state, but it goes against the informations that appears into the kml doesn't it ? This is that last step I don't really understand and don't know how to do it. Thanks again.
